Function

The CLOCK Step clock output is used to inform the Sequencer-Driver to perform a step. The direction

28

(clockwise or counterclockwise) is defined by the logic status of the DIR output. In steady conditions, the

CLOCK is at the ”one” logic level, and the step is represented by a negative going pulse with a 1.7µs

duration.

The HOME Home position input allows the system to find its reference point. This input can be driven by

30

a mechanically activated contact indicating the ”zero” position. It is normally used together with the EOT

End-of-travel signal.

The UO1 User output 1 is intended for user purposes. The status of this output can be set and cleared

31

under program control and it can be used for various functions. It is normally used for the control of

external devices, the selection of the Sequencer-Driver operating mode, or the synchronization of

complex movements.

The EOT End-of-travel input allows, in combination with the HOME input, the correct mechanical

32

initialization of the system. For this purpose it must be brought to the ”zero” logic level when the system

reaches the run end position.

33

The U02 User output 2 is intended for user purposes. See pin 31 description.

The UI1 User input is intended for user purposes. The status of this input can be read by the Host

34

Computer or tested during the program execution, and used to condition the start of a movement, the

execution of a specific portion of a program (GS-C200S only), or any other similar operation.

35

The UO3 User output 3 is intended for user purposes. See pin 31 description.

36

The UI2 User input 2 input is intended for user purposes. See pin 34 description.

37

The UI3 User input 3 input is intended for user purposes. See pin 3 and pin 4 description.

38

See pin 8.
